Answer:
The Humminbird 525 fishfinder is a nice unit, however, it is only rated at 200 Watts RMS.
Now, the higher the Watts the more depth you will read. Humminbird says 800 feet but I don't think that is likely.
They
do say that at 40 feet you will pick up a small jig and you have separation in targets by 2 1/2 inches. The transducer
is 200 khz which is OK but the cone angle is only 20 degrees, so you will be looking at a smaller area.
This unit is not like
the Vexilar's which can shoot directly thru the ice as long as the transducer is wet, so you will still have to drill a hole.
You can save yourself a lot of time by getting a hydrographic map of the lake your going to fish or ask the bait shop owner in the area where the shoals
are.
You can also cheat by watching where everyone else is fishing and at different times of the season. You might want
to invest in a hand held GPS and mark the waypoints using some kind of code so you know when you were there.
Also
a fish finder doesn't catch fish only lets you know if you wasting time in the area. Pay attention to the bottom readings and
learn to interpret what they mean. Each type of fish your going after has certain habits, so you'll have to do a
little reading. Hmmm, sounds like I have an article to write.

What is the best fish finder for the price? I have a 19 ft. boat on Lake Ontario. Depending on price, I'm looking for a fishfinder/gps combo or just a depth/fishfinder w/o the gps. Many Standard Fish Finder Features I'm considering a fairly top of the line fish finder/GPS unit for my bass boat. I am looking for a unit to tell me speed, water temp, and record waypoints. |
